I am balls deep in rebuilding my g10. Took a look at my EGR while I was in there. Thing looks like original since 1994. So clogged I don't think it's cleanable. seeing as its been burning oil for so long. I was thinking about just making a block off plate for it like I did on my last 2 sprints.

My question is seeing as there is a (what I guess to be) a coolant temp sensor attached to the EGR system. Will I need to unplug that or bypass it somehow? Or does it even matter? I would assume the engine would be running hotter as the EGR isn't getting exhaust gas pumped in. I mean hell the things been so clogged that I doubt it's been doing anything for quite some time and has been running ok. Aside from the obvious low compression issue and burn valves.

Soak the valve and it will clean up.The exhaust gases cool the combustion chambers, so your engine will run cooler if you fix your EGR.If it doesn't work, you'll lose compression due to high combustion temperatures and burn oil.

On the other hand, these two people thing you have a great idea:

They've never actually worked on a car, but hey...they LIKE the way you think outside the box.

Just a question. I understand how an egr works. And am aware cars ran with them before modern technology . What solution should it be soaked in? Simple green, clr? I am worried about damage to the diaphragm. And this thing is really clogged. As this is my daily and only ride to work. So getting it running asap is a must till I can afford other parts. I am no mechanic or claim to be one. I just read a lot. And can turn a wrench. I have worked on every car ivr owned. And without issues. Just because I am not ase certified. Doesn't make me a moron. If I can't clean it. I may just go buy a new one on Friday and replace it. Just wondered if there was a way around it till I could afford a replacement.

Lol. Fine I will post pictures. I did a little cleaning out of the main inner two holes and bottom. But its clogged inside. I'll try simple green. I have some left from what I used to soak the pistons.

Now take the time to heat up the Simple Green that's left over from when you soaked the pistons (too much information).And don't soak pistons in Simple Green ever again.Pistons have a coating which is attacked by it.You can spray the SG on and lightly scrub it with a soft toothbrush, but don't remove that expensive coating which the manufacturer put on the pistons to help them last.

Take little steps, and remember to show us your progress.We take our time for you, appreciate it.

hmmm. Didn't realize there was a coating on the pistons. And simple green would eat it. It got the carbon off. That's for sure.

Mine looked about as bad as the one you just showed. Completely clogged. I tried to clean it out with a screw driver (lightly as to not scratch the inside) But it is pretty cloggified.

I sure do appreciate it. Many people have helped me figure out problems and fixes that are engine specific here. Without this forum I would be lost sometimes. Many helpful people here. And I hope I have helped others with what knowledge I have shared in the past. We all want our tiny cars to last forever. And this place is a big help in making it happen.

Btw thank you for the info on the simple green. I will make sure in the future to only lightly use the stuff. And not drown it.
